Sia drops 'The Greatest' feat. Kendrick Lamar, video starring Maddie Ziegler

Sia teams up with an old friend and a new one on the latest single, "The Greatest," which dropped unexpectedly over the Labor Day weekend. The uplifting, poppy song with a subtle island vibe features a verse from Kendrick Lamar, who makes his presence known early with the lines, "I transform with pressure, I'm hands-on with effort/ I fell twice before, my bounce back was special/ Letdowns will get you and the critics will test you/ But the strongest survive another scar may bless you."

In another dance-heavy clip, the song's video features Ziegler leading a troupe of fellow children and adults in a joyous routine inside a dilapidated apartment buildings, moving from one room to another, with the usual compliment of expressive hand and facial gestures: Lamar does not appear in the clip.
